A new pressurized solar water heater

Abstract

The invention relates to the technical field of solar energy, and discloses a novel pressurized solar water heater, which includes a support seat, a water tank shell is fixedly connected to the top of the support seat, an inner tank is fixedly sleeved in the inner cavity of the water tank shell, and the bottom of the support seat A vacuum heat collecting tube is fixedly connected, and one end of the vacuum heat collecting tube runs through the outer shell and the inner tank of the water tank. In the present invention, through the designed thermal insulation spring and thermal insulation piston, when the tap water stops supplying water to the heat exchange tube, the thermal insulation piston can rebound and block the connection between the heat exchange tube, the water inlet pipe and the water outlet pipe, avoiding hot water in the heat exchange tube Combine the cold water in the water inlet pipe and the water outlet pipe for heat exchange, so that the heat preservation effect of the water heater is enhanced, and at the same time, the water outlet pipe loses the supply of subsequent water sources, so that the water in the water outlet pipe can be used first in daily water, so that residents can use it next time The hot water can be obtained directly when the water heater is used, which avoids the waste of water resources caused by the water discharge when the residents shower.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a novel pressure-bearing solar water heater. Background technique [0002] For the needs of environmental protection, more and more families begin to use solar water heaters. The existing solar water heaters are divided into two types: non-pressure type and pressure type. It needs to be placed in a relatively high place such as the roof, and the height difference is used to provide pressure, so that hot water can pass through the household, but this still has the disadvantage of insufficient water pressure. [0003] The pressurized solar water heater mainly uses the collector tube to heat the cold water in the water storage tank, and then uses the hot water to heat the heat exchange tube in the water storage tank to heat the cold water in the heat exchange tube. The pipe is connected with the water supply pipe network, so it can provide suitable water pressure, so that the ...
